How does the for-each loop work in statement 3?

Using the Enhanced for Loop You can use the enhanced for loop to cycle through an array of objects.

What is an enhanced for loop?

Enhanced for loop(for-each loop) This for-loop was introduced in java version 1.5 and it is also a control flow statement that iterates a part of the program multiple times. This for-loop provides another way for traversing the array or collections and hence it is mainly used for traversing array or collections.Feb 10, 2022

Is enhanced for loop better?

In general, enhanced for loop is much easier to use and less error-prone than for loop, where you need to manage the steps manually. At the same time, for loop is much more powerful because you get the opportunity to control the looping process.Sep 13, 2021

What are the advantages of using an enhanced loop?

MAJOR BENEFIT: This aids readability and clarity. To sum up, the enhanced for loop offers a concise higher level syntax to loop over a list or array which improves clarity and readability. However, it misses some parts: allowing to access the index loop or to remove an item.

When should you not use an enhanced for loop?
